On small scales the magnetic field is seen at the solar surface as a ubiquitous “salt-and-pepper” disorganized field that may be generated directly by the turbulent convection. On large scales, the magnetic field is …

Webnot capable of dynamo action. By applying a certain velocity field to a small magnetic field, it can be determined through observation whether the magnetic field tends to grow or not … WebAbstract. The existence of fast dynamos caused by steady motion of an electrically conducting fluid is established by consideration of a two-dimensional spatially periodic flow: the velocity, which is independent of the vertical coordinate z, is finite and continuous everywhere but the vorticity is infinite at the X-type stagnation points.
WebMar 24, 2016 · Mobile lid convection therefore favors dynamo action because it efficiently cools the mantle and thus boosts the core heat flow. Stagnant lid convection, on the other hand, can impede core cooling; stagnant lid convection on Venus is a leading hypothesis for why Venus lacks a magnetic field [Nimmo, 2002]. However, stagnant lid convection does ... WebThe following actions are supported by Amazon DynamoDB: ReadCapacityUnits The maximum number of strongly consistent reads consumed …
WebNov 15, 2007 · Dynamo action can fail at very large variation, where strong thermal winds disrupt the mechanism in this regime. If the Rayleigh number is too close to critical the dynamo can fail for low lateral variation, where the flow has a larger component driven by the boundary condition. Similarly, increased azimuthal flow at lower Prandtl numbers … WebA) dynamo action, like the Earth’s magnetic field. B) a mechanism entirely unique to Mercury. C) being close to the Sun. D) being a fossil remnant dating back to the distant past when the core was more liquid. Answer: A. Which of these theories seems to best explain the Moon’s origin?
